Method Details
-
setInternalID
Description copied from interface:LmdbValue
Sets the ID that is used for this value in a specific revision of the value store.- Specified by:
setInternalID
in interfaceLmdbValue
-
getValueStoreRevision
Description copied from interface:LmdbValue
Gets the revision of the value store that created this value. The value's internal ID is only valid when it's value store revision is equal to the value store's current revision.- Specified by:
getValueStoreRevision
in interfaceLmdbValue
- Returns:
- The revision of the value store that created this value at the time it last set the value's internal ID.
-
getInternalID
public long getInternalID()Description copied from interface:LmdbValue
Gets the ID that is used in the lmdb store for this Value.- Specified by:
getInternalID
in interfaceLmdbValue
- Returns:
- The value's ID, or
LmdbValue.UNKNOWN_ID
if not yet set.
-
getDatatype
Description copied from interface:Literal
Gets the datatype for this literal.If
Literal.getLanguage()
returns a non-empty value than this must returnrdf:langString
. If no datatype was assigned to this literal by the creator, then this method must returnxsd:string
.- Specified by:
getDatatype
in interfaceLiteral
- Returns:
- The datatype for this literal.
-
getCoreDatatype
Description copied from interface:Literal
CoreDatatype is an interface for natively supported datatypes in RDF4J. This includes, among others, the XML Schema datatypes and rdf:langString. CoreDatatypes are implemented as enums and more performant and convenient to work with than IRI-based datatypes. The constantinvalid @link
{@link CoreDatatype#NONE)
- Specified by:
getCoreDatatype
in interfaceLiteral
- Returns:
- The CoreDatatype or
invalid @link
{@link CoreDatatype#NONE)
-

-
getLanguage
Description copied from interface:Literal
Gets the language tag for this literal, normalized to lower case.- Specified by:
getLanguage
in interfaceLiteral
- Returns:
- The language tag for this literal, or
Optional.empty()
if it doesn't have one.

equals
Description copied from interface:Literal
Compares this literal to another object.- Specified by:
equals
in interfaceLiteral
- Overrides:
equals
in classAbstractLiteral
- Parameters:
o
- the object to compare this literal to- Returns:
true
, if the other object is an instance ofLiteral
and if their labels, language tags and datatypes are equal
-
hashCode
public int hashCode()Description copied from interface:Literal
Computes the hash code of this literal.- Specified by:
hashCode
in interfaceLiteral
- Overrides:
hashCode
in classAbstractLiteral
- Returns:
- a hash code for this literal computed as
Literal.getLabel()
.hashCode()
-
toString
- Overrides:
toString
in classAbstractLiteral
-
writeReplace
- Throws:
ObjectStreamException
